' Specification of Letters Patent.

Patented Aug. 20, 1907.

' Application filed April 12,1907. Serial No. 367,729,

.To all whom it may concern:

\ Be it'kno'wn that I, Gnonei: O. LANDIS, a citizen of the United States, residing at Connellsville, in the county of Fayette and State of Pennsylvania, haveinvented or discoverednew and'useiul Improvements-in Coke-Ovens, of which the following is av specification.

' My invention relates to coke. ovens and more particularly to those having their rear ends located against banks or other coke ovens or othersabutments.

In ovens ofthis typeit has'not been practicable heretofore to supply air through the rear ends thereof, Be- 7 cause they were closed or made inaccessible by reason of said banks, ovens or abutments.

I It is the principal object of my invention to produce 5 coke-ovens of said type, which may be suppliedwith air at both'the front and the rear ends The-ovens may be internally of any desired figure,

but I prefer that the sides shallbe slightly flared from rear to front, so that the coke in the oven may be drawn out in a single mass without binding on the said sides. Of course, some of the advantages of my oven may beob tained with the sides parallel or curved outwardly.

' Referring to the drawings, Figure 1 is a central longitudinal section of one form 'ofcoke oven to which my improvements may be applied; Fig; 2 a front ele- 'vation of said oven; Fig. 3', ,a section on the line 33 I of Fig. 1; and

Fig. 4, a horizontal section on a reduced scale. 1

On the drawings, 1 represents thefloor of the'oven and 2, the parallel sides. thereof. The rear end of the oven is closed by the wall 3, and the top, by the preferably. arched roof 4, havingdthe trunnel or charging hole 5 in the center thereof.

, The front 6 of the oven included by the floor l, the

.two side walls 2 and the top of, the arch 7, which is snbstantially at the level of the lowest portion of the roof 4, is bricked in as shown in Fig. 2 or provided with a door, so as to leave an air inlet just below the arch 7 as shown in 2, the said inlet being marked 8.

The rear wall 3 is built double, the rear section 9 entirely closing the rear end of the oven while the front section 10, which is parallel to the rear section and separated therefrom by-the space or flue 11, is shorter than the rear section, a space 12 being leftat the top of the front section, which space preferably is at-the level of with such slots as 8 in their rear ends.

or space.8, an additional supply of air is led into the oven through the slot or space 12, which is in cornmunication with the external air by means of the space or flue 11 and the flue 13. The direction of the air currents is shown by the arrows on the said flues.

By means of my invention ovens of the type described can be supplied with air at both ends, as well as if the ends ofthe ovens were accessible or provided air to both ends of the ovens, the combustion is more uniform throughout the oven and the usual dead space always existing at the rear ends of the usual oven which takes air from the front only is made as active in the coking operation as the space in front of the trunnel holes.

It will be observed from Fig. 4 that the coke can be withdrawn readily from the oven without liability of binding on the sides, thereof, becausethey are flared from rear to front. It is only necessary that a suitable y pp y g drawing tool" be engaged with the rear. side of coke,

when, by the application of sufficient force to the tool, the entire charge may be withdrawn at one operation.

I clainn I In a coke oven, a roof having a central opening, a floor having an air flue extending from the front to the rear thereof, a front wall, a rear wall of two parallel sections s lacedapart to form a vertical air passage as vide as the rear wall and connected to the flue in the floor, the-front -wall having an opening leading directly from the external air into the front end of the oven and the front section of the rear wall being of less heightthan the rear section, whereby a sheet 'of air the width of the rear wall mayenter therear end of the oven.
